[mvapich-discuss] MVAPICH Error

[OShea, Thomas T.]

As it turns out my system admin tells me that the installation of open
fabrics wasn't complete enough, once he fixed that it installed without
a hitch.

With this new 1.0-beta version I'm not getting that error any longer.
Although, run times seem to be a bit longer; but we are still
investigating that.

Thanks for you help.

Tom

Sorry to know that you are having trouble compiling 1.0-beta. Could
you please let us know the exact error you are seeing. It will help us
to solve this problem. We have not seen any such errors on our
systems.

Thanks for this information. We will investigate the assertion error
issue.

Thanks,
